基于等效连续介质渗流模型及多孔介质多场耦合理论，建立裂隙水作用下的巷道围岩体温度场计算的物理模型，建立裂隙水渗流场、裂隙水温度场、岩体温度场耦合控制方程，辅以边界条件参数，以FLUENT软件进行数值模拟，研究了裂隙水渗流作用下的矿井巷道围岩体温度场分布。结果表明，裂隙水的迁移伴随着热量的交换，裂隙水的作用改变了巷道围岩体的温度场分布；定量分析了裂隙水渗流速度对两者温度场分布的影响，在裂隙水流动方向上，渗流速度愈小，则裂隙水流温升愈大，围岩温度温升愈大；当裂隙水渗流速度大于2×10-8 m/s时，其变化对巷道围岩体温度场分布有着显著的影响；但渗流速度小于2×10-8 m/s时，影响是微小的。

Based on the equivalent continuous medium model and the multi -field coupling theory,the physical model of temperature field calculation of roadway surrounding rock under the action of fracture water, the seepage field and temperature field of the rock,and the coupling control equation are established.Through the parameter of boundary conditions,the numerical simulation is carried out with software FLUENT.The temperature distribution of roadway surrounding rock under the action of fracture water is revealed.The analysis shows that the migration of fracture water accompanies the heat exchange and the action of fracture water changes the temperature distribution form of roadway surrounding rock.The influence of seepage velocity of fracture water on the temperature distribution of both fracture water and roadway surrounding rock is analyzed quantificationally. In the flow direction of fracture water,the smaller the seepage velocity is,the greater the temperature rise of fracture water and surrounding rock are.When the flow velocity is greater than 2 ×10 -8 m/s,the changes of seepage velocity have a significant impact on the temperature distribution of roadway surrounding rock.However, when the flow velocity is smaller than 2 ×10 -8 m/s,the effect is slight.
